Ok, we are at day 21 with 17 eggs in the little giant still air incubator. We have three rocking back and forth and another one that has cracked. We are hearing very loud chirping! It has been chirping since about 5 or 6 am this morning. I don't want to be a worry wart or do something stupid by messing with the eggs. So, is this normal? And when should I worry? I read the article by Miss Sunshine, but being new to this and not wanting to sound too stupid, I wasn't sure. Thanks for all your info and help!
